BACKGROUND:There are safe and well-tolerated level A evidence-based behavioral therapies for the prevention of migraine. They are biofeedback, cognitive behavioral therapy, and relaxation. However, the behavioral therapies for the prevention of migraine are underutilized. OBJECTIVES/OBJECTIVE:We sought to examine whether people with migraine with 4 or more headache days a month had preferences regarding the type of delivery of the behavioral therapy (in-person, smartphone based, telephone) and whether they would be willing to pay for in-person behavioral therapy. We also sought to determine the predictors of likelihood to pursue the behavioral therapy. METHODS:Using a cross-sectional study design, we developed an online survey using TurkPrime, an online survey platform, to assess how likely TurkPrime participants who screened positive for migraine using the American Migraine Prevalence and Prevention screen were to pursue different delivery methods of the behavioral therapy. We report descriptive statistics and quantitative analyses. RESULTS:There were 401 participants. Median age was 34 [IQR: 29, 41] years. More than two thirds of participants (70.3%, 282/401) were women. Median number of headache days/ month was 5 [IQR: 2.83, 8.5]. Some (12.5%, 50/401) used evidence-based behavioral therapy for migraine. The participants reported that they were "somewhat likely" to pursue in-person or smartphone behavioral therapy and behavioral therapy covered by insurance but were neutral about pursuing the telephone-based behavioral therapy. Participants were "not very likely" to pay out of pocket for the behavioral therapy. Migraine-related disability as measured by the MIDAS grading score was associated with likelihood to pursue the behavioral therapy in-person (P = .004), via telephone (P = .015), and via smart phone (P < .001), and covered by insurance (P = .001). However, migraine-related disability was not associated with likelihood to pursue out of pocket (P = .769) behavioral therapy. Pain intensity was predictive of likelihood of pursuing the behavioral therapy for migraine when covered by insurance. Other factors including education, employment, and headache days were not predictors. CONCLUSION/CONCLUSIONS:People with migraine prefer in-person and smartphone-based behavioral therapy to telephone-based behavioral therapy. Migraine-related disability is associated with likelihood to pursue the behavioral therapy (independent of type of delivery of the behavioral therapy-in-person, telephone based or smartphone based). However, participants were not very likely to pay for the behavioral therapy.

PURPOSE/OBJECTIVE:To assess the relationship between depressive symptoms and self-perceived severity of autonomic dysfunction in patients with multiple system atrophy (MSA). METHODS:Cross-sectional evaluation of patients with MSA who underwent autonomic testing, Unified MSA Rating Scale (UMSARS)-1 and -2, rating of the presence and severity of depressive symptoms (Zung scale), quality of life (SF-36), body vigilance, anxiety (Spielberger's anxiety scale), severity of autonomic dysfunction with the Composite Autonomic Symptoms Score (COMPASS-31), and severity of orthostatic hypotension (OH) symptoms with the Orthostatic Hypotension Questionnaire (OHQ). RESULTS:Fifty-eight patients (32 women) with probable MSA (aged 61.8 ± 8.6 years; disease duration 4.3 ± 2.1 years) were studied. Forty patients (69%) had symptoms of depression in the Zung scale. Age, disease duration, and motor disability were similar in those with and without symptoms of depression. Despite a similar orthostatic blood pressure fall, the severity of orthostatic symptoms was higher in patients with symptoms of depression (p = 0.004). Depression scores were associated with higher burden of autonomic symptoms (R = 0.401, p = 0.02), specifically with the COMPASS-31 items related to orthostatic intolerance (R = 0.337, p = 0.045), and with the OHQ (R = 0.529; p < 0.001). A multivariable regression model including age, sex, UMSARS, and drop in systolic blood pressure upon head-up tilt as covariates showed that the burden of depressive symptoms was independently associated with the OHQ score: for every 1-unit increase in the Zung depression score, there was a 1.181-point increase in the total OHQ score. CONCLUSIONS:In patients with MSA, depressive symptoms worsen the perceived severity of autonomic symptoms in general and orthostatic hypotension in particular. Our findings have implications for clinical trial design.

BACKGROUND AND PURPOSE/OBJECTIVE:The Neuroform Atlas is a new microstent to assist coil embolization of intracranial aneurysms that recently gained FDA approval. We present a postmarket multicenter analysis of the Neuroform Atlas stent. MATERIALS AND METHODS/METHODS:On the basis of retrospective chart review from 11 academic centers, we analyzed patients treated with the Neuroform Atlas after FDA exemption from January 2018 to June 2019. Clinical and radiologic parameters included patient demographics, aneurysm characteristics, stent parameters, complications, and outcomes at discharge and last follow-up. RESULTS:= .03). CONCLUSIONS:This multicenter analysis provides a real-world safety and efficacy profile for the treatment of intracranial aneurysms with the Neuroform Atlas stent.

Persons who have disorders of consciousness (DoC) require care from multidisciplinary teams with specialized training and expertise in management of the complex needs of this clinical population. The recent promulgation of practice guidelines for patients with prolonged DoC by the American Academy of Neurology (AAN), American Congress of Rehabilitation Medicine (ACRM), and National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) represents a major advance in the development of care standards in this area of brain injury rehabilitation. Implementation of these practice guidelines requires explication of the minimum competencies of clinical programs providing services to persons who have DoC. The Brain Injury Interdisciplinary Special Interest Group of the ACRM, in collaboration with the Disorders of Consciousness Special Interest Group of the NIDILRR-Traumatic Brain Injury Model Systems (TBIMS) convened a multidisciplinary panel of experts to address this need through the present position statement. Content area-specific workgroups reviewed relevant peer-reviewed literature and drafted recommendations which were then evaluated by the expert panel using a modified Delphi voting process. The process yielded 21 recommendations on the structure and process of essential services required for effective DoC-focused rehabilitation, organized into four categories: Diagnostic and Prognostic Assessment (four recommendations), Treatment (eleven recommendations), Transitioning Care/Long Term Care Needs (five recommendations), and Management of Ethical Issues (one recommendation). With few exceptions, these recommendations focus on infrastructure requirements and operating procedures for the provision of DoC-focused neurorehabilitation services across subacute and post-acute settings.

OBJECTIVE:To systematically identify risk factors for the development of post-traumatic headache (PTH) attributed to traumatic brain injury (TBI) as defined in the International Classification of Headache Disorders (ICHD). BACKGROUND:PTH is a common sequela of TBI and a leading cause of injury-related disability worldwide. However, little is known about risk factors for the development of PTH attributed to TBI. METHODS:We searched PubMed and Embase for literature on risk factors for the development of acute and/or persistent PTH attributed to TBI in accordance with any version of the ICHD. Original studies published in English and of prospective, cross-sectional or retrospective design were considered for the review. Data extraction was performed independently by 2 investigators. RESULTS:Of 1993 potentially relevant articles identified, 3 articles met the inclusion criteria. The following risk factors were assessed for the development of acute PTH: age, sex, type of injury, loss of consciousness, previous TBIs, history of primary headache disorders, history of chronic pain condition other than headache, current treatment for depression/anxiety, attention or learning disorders, body mass index, and other diseases (not further specified). None of the included studies assessed risk factors for the development of persistent PTH. CONCLUSIONS:We found that there is little evidence for any risk factors involved in the development of acute PTH, whereas no study had assessed risk factors for the development of persistent PTH. Further studies are warranted and should be powered to examine possible risk factors for the development of PTH. Rigorous methodology and standardized monitoring should be prioritized to support high-quality research and validate potential findings.

Almost all medical care in the United States is delivered with the provider and patient in immediate proximity; this model is referred to as face-to-face care. Medical services can be apportioned as procedural care (eg, surgery, radiology, or laboratory testing and others) or cognitive care, also known as Evaluation and Management (E/M) services, in which the provider formulates an assessment and plan after obtaining information from the patient's history, examination, and diagnostic tests.Providing a medical opinion and plan using the telephone as the technology that links the provider and the patient is an example of a non-face-to-face E/M service. Common Procedural Terminology (CPT) codes and the details for how to provide telephone services have been available for decades but have not been reimbursed and therefore were rarely used. In recent years, as new technologies have evolved, there has been slow and steady acceptance that non-face-to-face E/M care can be an adjunct to or replacement for some face-to-face E/M services. These technologies and the descriptors for associated CPT and Healthcare Common Procedure Coding System (HCPCS) codes were introduced over the past few years and have become known by the generic term telehealth. They have been slowly incorporated into medical practice. Most of these services were introduced in the consumer retail market, in which the cost was borne directly by the patient, or as private contract services, in which the cost was borne by the consulting hospital, such as with telestroke services. In both the consumer retail model and private contract model, the care delivered usually did not involve CPT or HCPCS coding. The adoption of telehealth has been slow, in part because of the initial costs and several regulatory constraints, as well as the reluctance of patients, providers, and the insurance industry to change the concept that medical care could only be delivered when the patient and their provider were in physical proximity.After the COVID-19 pandemic reached the United States, the US Department of Health & Human Services issued a public health emergency and declared a Section 1135 Waiver that lifted many of the administrative constraints. With the need for near-absolute social distancing, this perfect storm has resulted in the immediate adoption of telemedicine, at least for the duration of the pandemic, for cognitive care to be delivered using communication technologies that are already in place. This article discusses the most common forms of non-face-to-face E/M care and the proper coding elements necessary to provide these services.

BACKGROUND:Sleep disturbances and nocturnal hypokinesia are common in Parkinson's disease (PD). Recent work using wearable technologies showed fewer nocturnal movements in PD when compared with controls. However, it is unclear how these manifest across the disease spectrum. OBJECTIVES:We assessed the prevalence of sleep disturbances and nocturnal hypokinesia in early and advanced PD and their relation to nonmotor symptoms and dopaminergic medication. METHODS:A total of 305 patients with PD with diverse disease severity (Hoehn and Yahr [H&Y] stage 1 = 47, H&Y stage 2 = 181, H&Y stage 3 = 77) and 205 healthy controls continuously wore a tri-axial accelerometer on the lower back for at least 2 days. Lying, turning, and upright -time at night were extracted from the acceleration signals. Percent upright time and nighttime walking were classified as sleep interruptions. The number, velocity, time, side, and degree of rotations in bed were used to evaluate nocturnal movements. RESULTS:Nocturnal lying time was similar among all groups (healthy controls, 7.5 ± 1.2 hours; H&Y stage 1, 7.3 ± 0.9 hours; H&Y stage 2, 7.2 ± 1.3 hours; H&Y stage 3, 7.4 ± 1.6 hours; P = 0.501). However, patients with advanced PD had more upright periods, whereas the number and velocity of their turns were reduced (P ≤ 0.021). Recently diagnosed patients (<1 year from diagnosis) were similar to controls in the number of nocturnal turns (P = 0.148), but showed longer turning time (P = 0.001) and reduced turn magnitude (P = 0.002). Reduced nocturnal movements were associated with increased PD motor severity and worse dysautonomia and cognition and with dopaminergic medication. CONCLUSIONS:Using wearable sensors for continuous monitoring of movement at night may offer an unbiased measure of disease severity that could enhance optimal nighttime dopaminergic treatment and utilization of turning strategies. © 2020 International Parkinson and Movement Disorder Society.

Cell death is prevalent throughout life; however, the coordinated interactions and roles of phagocytes during corpse removal in the live brain are poorly understood. We developed photochemical and viral methodologies to induce death in single cells and combined this with intravital optical imaging. This approach allowed us to track multicellular phagocytic interactions with precise spatiotemporal resolution. Astrocytes and microglia engaged with dying neurons in an orchestrated and synchronized fashion. Each glial cell played specialized roles: Astrocyte processes rapidly polarized and engulfed numerous small dendritic apoptotic bodies, while microglia migrated and engulfed the soma and apical dendrites. The relative involvement and phagocytic specialization of each glial cell was plastic and controlled by the receptor tyrosine kinase Mertk. In aging, there was a marked delay in apoptotic cell removal. Thus, a precisely orchestrated response and cross-talk between glial cells during corpse removal may be critical for maintaining brain homeostasis.
